I just wish I had an immediate use for an 800 it looks like such a great chip. But I'm up to my arse writing low-level drivers for the LPC1227 at present.

I know, I'm trying to figure out something too. I did go so far as to download the datasheet and user's guide. I might have to try one out anyway. If a person wanted to get started with LPCs, do you think the LPC812 is as good as any, or is there a model you'd suggest? I'm really interested to see the pricing on these chips, I wonder how far off they are. The datasheet still has some TBDs in the electrical characteristics! The switch matrix is a very cool feature, I've wondered whether anyone did such a thing; now I know. Makes the 8-pin DIP a little more understandable, I think I'd still go for one of the 20-pin packages just for general goofing around though.

Probably, although it's note available yet. Although as was pointed out above the LPCXpresso board is and to start with that's all that matters. The LPCXpress system is very good.

Well I'm pretty much into the LPC1227, at 48 or 64 pins and with 2 UARTs I find it's about right for what I'm doing now. I liken it to the Mega1284 which I think is the best AVR around. I like those chips so much my current PCB has one of each

I've written a lot of code for the 1227, originally just to learn the chip but it's slowly turning into a proper Arduino-style HAL. See here

I was reading a bit on the ARM architecture the other evening, found this in a Wikipedia article. I thought, only 35,000? Wow! Contrast to 1.4B transistors in Intel's Ivy Bridge chips. Not exactly an apples-to-apples comparison, but the gap in performance is much less than the transistor counts might lead a person to believe.

Using the RISC approach, the core ARM processor requires only 35,000 transistors, compared to the millions in many conventional processor chips, resulting in lower power usage and making it very attractive in smaller devices.

I've often wondered about the ATtiny and ATmega chips, but have never seen a transistor count for them.

Looks like the LPC81xM chips are getting closer, Mouser now lists them as on order, although no delivery dates. Prices (single quantities) range from $0.78 for the LPC810 to $1.16 USD for the most expensive LPC812. Unfortunately the development board went up from $15.00 to $18.75 since I last checked. I may just order one up anyway. I also discovered that the free LPCXpresso IDE only does C, not C++. Major bummer.

Yeah the free version is 128K, which as you say doesn't seem like much of a restriction. Then there are 256K and 512K versions, for $256 and $512 respectively. Cute. Obviously not a serious pricing policy, I wonder what they were thinking.
